By combining photo-electrochemical and photo-induced microwave conductivity measurements, information on potential dependent minority charge carrier accumulation, on interfacial minority carrier concentration and on interfacial charge transfer rates can be obtained.
Regression models of censored survival data are often required to handle the cases, where information on the dependent (response) variable is only available as intervals, within which the actual values are located.
While auxiliary data allow researchers to examine the nature of measurement error, these data typically do not contain information on the dependent variable of interest.
We exclude 101 persons who were not wage earners at the beginning of the sick leave, 71 persons with missing information on the dependent variables, and 6 persons with missing information on the covariates.
The information on the dependent variable is which of these K intervals it falls into, i.e., an indicator variable k i (1 ≤ k i ≤ K) is observed for each i.
To avoid running a regression where information on the dependent variable (collected for the entire year) precedes the recording of the explanatory variables (collected in October), all explanatory variables in Eqs.
Patient observations with missing information on the dependent variable were excluded.
Information on the dependent variable, SRH, was obtained by asking respondents the question: "Generally how do you describe your own health: excellent, good, normal, bad, or very bad".
Information on the dependent variable came from the company's worker's compensation claim database for the study population between January 2003 and December 2010.
Regression analyses were performed in observations with complete information on the dependent and all independent variables at each measurement (n = 61).
